satellite DNA
Tandem repeat regions
Satellite DNA is repetitive genetic material that doesn't code for proteins, instead forming long stretches of repeated sequences in chromosomes.
The name comes from how these sequences separate from the main DNA band during centrifugation, appearing as distinct "satellite" bands.
Satellite DNA plays roles in chromosome structure and cell division: Researchers studied the satellite DNA near the centromere.
